Embodiment approach

[0120] In a specific implementation manner, in order to improve the accuracy of step counting processing, at least two kinds of sensor data can be used to perform step counting processing on the user, and further filter processing can be performed on the sensor data to filter out noise in the sensor data, further Improve the accuracy of step counting processing, and improve the accuracy of subsequent user positioning based on step counting results. Based on this, an implementation manner of the above step 501 includes:

[0121] Collect at least two kinds of sensor data reflecting the motion state of the terminal equipment in real time;

[0122] performing filter processing on at least two kinds of sensor data respectively to obtain filtered sensor data;

[0123] According to the filtered sensor data, step counting processing is performed on the user to obtain at least two time periods in which the user moves and a moving direction corresponding to each time period in the at l...

Abstract

The present application provides a fingerprint database construction method, positioning method and device. A fingerprint database construction method includes: receiving a service request sent by each client that has a business relationship with a target service object, and receiving location fingerprint data sent by each client in the process of sending the service request; determining the location of the target service object according to indication information. The location of the target business object is taken as the location point corresponding to the fingerprint data of each location; according to the fingerprint data of each location, the fingerprint feature corresponding to the location point is obtained, and the corresponding relationship between the location point and the fingerprint feature is established to generate the fingerprint database. The present application can improve the accuracy of indoor positioning.

Description

【Technical field】 [0001] The present application relates to the field of communication technology, and in particular to a method for constructing a fingerprint database, a positioning method and a device. 【Background technique】 [0002] The Global Positioning System (Global Positioning System, GPS) is widely used in various industries, but it also has an obvious defect, that is, poor indoor positioning, which cannot meet the coverage and accuracy requirements of indoor positioning. Therefore, a positioning method based on Wi-Fi signals and / or base station signals has emerged. [0003] The method flow of positioning based on Wi-Fi signals and / or base station signals is as follows: the mobile terminal can detect nearby base station signals and / or WI-FI signals, and send the base station signals and / or WI-FI signals to the server, and the According to the base station signal and / or WI-FI signal, the server queries the corresponding location points in the fingerprint database s...
